They probably were given a command to stay at 4000 above ground (AGL) level after takeoff. The plane was to level off until further instructions from ATC. Since the plane was set to sea level on takeoff, the plane tried to level off at 4000 ft above sea level which…is not good. The plane was pitched down to descend.
- csunbird 5y agoOh no. So, the computer was actually trying to keep the plane pitched down to avoid ascending naturally and keep the altitude stable. This is really, really bad.
- jackweirdy 5y agoWell, the autopilot was disabled, and the flight director (which at a 1 sentence level is a visual indication of what the autopilot would do) was trying to keep the plane level at the configured altitude The flight director did the right thing — displayed how it would manage level flight The pilot did the wrong thing - copied the misconfigured flight director instead of flying the plane
- elihu 5y agoIsn't the airport in Dubai barely above sea level anyways? I mean, if the difference between ground level and sea level is less than a hundred feet, then it seems like it wouldn't account for a plane thinking it was at 4,000 feet when it was really at about 200.
- t0mas88 5y agoPilot here. This is completely wrong, nobody ever gives altitude instructions above ground level. That doesn't exist in ATC terms.
